安装特定的 PyTorch 版本（pytorch==1.0.1）

Question

我正在尝试在 conda 环境下安装特定的 PyTorch 版本：

使用 pip：

pip3 install pytorch==1.0.1
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.
Defaulting to user installation because normal site-packages is not writeable
ERROR: Could not find a version that satisfies the requirement pytorch==1.0.1 (from versions: 0.1.2, 1.0.2)
ERROR: No matching distribution found for pytorch==1.0.1

使用康达：

conda install pytorch==1.0.1
    Collecting package metadata (current_repodata.json): done
    Solving environment: failed with initial frozen solve. Retrying with flexible solve.

我能够在 https://anaconda.org/soumith/pytorch 下找到这个版本，但是有没有办法找到它并从控制台安装？

Answer 1

你可以download/install你喜欢的官方版本Pytorch's Conda package。您指定的 link 是旧版本，不是 supported/updated 现在退出一段时间！
像这样安装你想要的版本：

conda install pytorch==1.0.1 torchvision==0.2.2 -c pytorch

如果您正在寻找 pip 版本，您也可以查看和访问来自 here 的所有版本。

然后简单地做：

pip install torch===1.0.1 -f https://download.pytorch.org/whl/torch_stable.html

您也可以随时在此处查看 previous versions。

Answer 2

您可以使用以下任一方法下载以前版本的 pytorch： 针对Linux/Windows具体OS

# CUDA 9.0
conda install pytorch==1.0.1 torchvision==0.2.2 cudatoolkit=9.0 -c pytorch

# CUDA 10.0
conda install pytorch==1.0.1 torchvision==0.2.2 cudatoolkit=10.0 -c pytorch

# CPU Only
conda install pytorch-cpu==1.0.1 torchvision-cpu==0.2.2 cpuonly -c pytorch
